EWERTZ, OF ELIZABETH, NEW JERSEY VESSEL Application filed January 20, 1930, Serial No. 421,883. Renewed January 15, 1931.

This invention relates to an improved vessel of the barge type and has for its object to provide a vessel, the hull of which is constructed in its entirety of flanged metal plates, preferably electrically welded together to form an integral structure which will be very light and strong and at the same "time inexpensive to construct.

Another object of the invention is to pro- Vide a vessel having in addition to the longitudinal and transverse bulkheads, a double bottom and double sides in order that a better protection may be provided for the cargo that is carried, the inner shell which forms the .15 inner bottom andsides consisting of L- shaped' angle plates arranged side by side and secured to the outer shell and to each other in such a manner that they will, in effect, constitute a succession of 'U-shaped 2.0 ribs all having flat intermediate portion so joined together that they will form a continuous inner shell for the vessel.

The invention consists in a vessel constructed as set forth in the following specification and particularly as pointed out in the claims.

Referring to the drawings:

Figure 1 represents a plan view of avessel embodying by invention, a portion thereof being broken away and illustrated in section.

Fig. 2 is a sectional elevation taken on the line 22 of Fig. 1.

Fig. 3 is a detail horizontal section taken on the line 33 of Fig. 2.

. 5 Fig. 4 is a detail vertical section taken on the line H of Fig. 2.

Figs. 5 and 6 are sectional views illustrating modified embodiments of the invention.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, 10 represents the outer shell of a vessel consisting of a plurality of plates, 11, each having a flange 12 at one edge thereof extending inwardly. The side 5 of the flange abuts against the flangeless edge.

of the adjacent plate and the two are fastened together to make a watertight joint by electric welding.

The plates 11 extend along the sides and the bottom of the vessel and the adjacent ends of successive plates where they abut together are welded so that, in effect, each plate is continuous and extends from the bow to the stern of the vessel.

The interior of the outer shell 10 is divided 5.; into a plurality of compartments 13 by means of a plurality of longitudinal bulkheads 1 and transverse bulkheads 15, and said bulkheads are strengthened and given added rigidity by means of vertical angle plates 16 (so which are welded to the bulkheads.

Located within the outer shell 10 is an inner shell 17, the latter being spaced a suitable distance apart from the side portion of the outer shell to form an inner side wall 18 05 and also being spaced a suitable distance above the bottom of the outer shell to form an inner bottom 19.

The inner side wall 18 embodies therein a plurality of vertical L-shaped angle plates 20 which extend from the bottom of the outer shell 10 to the deck of the vessel, and said angle plates are positioned side by side with a side 21 of each plate extending perpendicular to the inner surface of the outer shell 10, theedge of said side portion being secured .to the outer shell at 22, preferably by welding. Another side portion 23 of each angle plate extends perpendicular to the side 21 of said plate and is secured to the corner portion of so the adjacent angle plate at 24 by welding. The side portions 23- of each angle plate 20 are all so connected together that they cooperate with each other to form a continuous inner wall or shell for the side portion of the 8 vessel, see Fig. 3.

The inner shell 17 also embodies therein a plurality of horizontal L-shaped angle plates 25 which extend transversely across the vessel between the inner side walls 18 thereof and the bulkheads 14 and said plates are positioned side by side along the entire inner bottom surface of the outer shell 10,

a side portion'26 of each plate being positioned perpendicular to the inner bottom surface of the outer shell 10, and the edge of said side portion being welded to the outer shell at 27. A side portion 28 of each angle plate 25 is perpendicular to the side 26 thereofzand is secured to a corner portion of the 109 adjacent angle plate at 29 by Welding. The side portions 28 of the angle plates 25 are all so connected together that they co-operate with each other to form a continuous inner wall or shell for the bottom portion of the vessel, see Fig. 4.

The angle plates and afterthey have been welded together and to the outer shell 10, in efiect, constitute U-shaped ribs and act to stiffen the hull and produce a very rigid and strong construction, and at the same time the side portions 23 and 28 of said plates are joined together in such a manner that they will constitute the inner sides and bottom of the inner shell 17.

The deck portion of the vessel may be constructed in any suitable manner, but preferably it is constructed of the same type of flanged plates that are employedin the construction of the outer shell 10, and these plates may be reinforced by any suitable form of flanged plate that may be desired.

In Fig. 5 I have illustrated a modified embodiment of my invention in which a plurality of angle plates 30 are positioned side by side with a side portion 81 thereof positioned perpendicular to the inner surface of the outer shell 10, and being secured thereto in any suitable manner but preferably by W616i"? ing and with a side 32 thereof extending perpendicular to the side 31 andwith a narrow flange 33 extending perpendicular to the side 32, and being secured either by riveting or welding to the side portion 81 ofthe adjacent angle plate; In this form of the inven tion the side portions 32 of the angleplates 30 co-ooerate to form a continuous wall for the inner shell.

In Fig. 6 I have illustrated another ernbodiment of my invention in which a plurality of angle plates 34 are positioned side by side with a side portion 35 thereof extending perpendicular to the inner surface of the outer shell 10 and being secured thereto in any suitable manner but preferably by welding, and with a side portion 36 thereof extending perpendicular to the side portion 35 and being bent slightly at 37 and overlapping the sideportion 36 of the adjacent angle plate 34 and being secured thereto either by riveting as illustrated at 38, or by welding as illustrated at 39. In this form of'the invention, the side portions 36 of the angle plates 34, in effect, constitute a' continuous inner wall for. the inner shell, although the smooth surface of said inner wall is broken by reason of the fact that the side portions 36 overlap each other.
